HARRY F. BUSHONG, OF KALAMAZOO, MICHIGAN, ASSIGNOR, BY MESNE ASSIGNMENTS, TO KALAMAZOO LOOSE LEAF BINDER COMPANY, A COR- PORATION.

Specification of Letters Patent.

Patented April 23, 1907.

Application filed August 5, 1904:. Serial No. 219,626.

To all whom it may concern:

Be it known that I, IIARRY F. BUSHONG, a citizen of the United States, residing at the city of Kalamazoo, county of Kalamazoo,

State of Michigan, have invented certain new and useful Improvements in Tem orary Binders or Loose-Sheet Holders, of which the following is a specification.

This invention relates to improvements in I0 temporary binders or loose sheet holders.

It is an adaptation of, and, in some respects, an improvement u ion my temporary binder or loose sheet holder illustrated and described in my application for patent filed concurrently herewith.

The objects of this invention are :Fi.rst,'

to provide an improved temporary binder or loose sheet holder adapted to receive and retain any number of sheets or leaves from one to its maximum capacity. Second, to provide an im roved temporary binder or loose sheet hol er from which any articular sheets or leaves may be quickly and easily removed and other sheets or additional sheets inserted. Third, to provide an im roved temporary binder or loose sheet ho der in which the adjusting devices may be quickly and readily sealed or rendered inaccessible if desired.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure embodying the features of my invention is clearly illustrated in the accompanying drawing forming a part of this specification, in which- Figure 1 is a plan view from the inside of my improved temporary hinder or loose sheet holder in its open position, the covers or closures b for the chamber containing the binding adjusting means being removed. Fig. 2 is an enlarged longitudinal sectional view taken on a line corres ending to line 2 2 of Fig. 1 of my improvet temporary binder or loose sheet holder in its closed position. Fig. 3 is an enlarged transverse sectional view, taken on a line corresponding to line 3 3 of Fig. 1, showing the adjusting means, the threaded shaft C being shown in full lines. Fig. 4 is an enlargeddetail sectional view taken on line corresponding to line 4 4 of Fig. 1, showing the locking means for the lid or closures b for enclosing the adjusting mechanism.

In the drawing, the sectional views are taken looking in the direction of the little arrows at the ends of the section lines, and similar letters of reference refer to similar parts throughout the several views.

Referring to the drawing, the covers A A which are preferably of some flexible material, such as leather, are provided. These covers are secured to the clamping bars B B. The cover A is provided with a pocket opening at its inner end, adapted to receive the end of the back piece a. The back piece a, is preferably connected to the clam ing bar of the other cover or an extension of t 1e cover A.

The clamping bars B B are ada ted to clamp the leaves or sheets to be held as E, between them,sec Figs. 1 and 2. These clamping bars B B are each provided with a longitudinal chamber and have holes I) in their inner or clamping faces, opening into the said chambers. Arranged through these holes I) is a binding cord l). The ends of this binding cord are secured to the blocks C which are threaded upon the adjusting shaft (1. This shaft U is arranged in suitable bearings as c in the clamping bar B. The shaft (1 is provided with right and left hand threads for the blocks 0 so that the ends of the binding cord are both adjusted by the rotation of this shaft.

F or some purposes, as in certain public records, it is desired to seal or enclose the adjusting niechanisn'i so that none of the sheets can be removed. I accomplish this by means of the lids or closures b which are adapted to slide in suitable ways provided therefor in the clamping bars,see Fig. 2. Locking dogs a, which are, held normally upward by the springs e are provided. These locking dogs are adapted to engage suitable notches under the faces of the lids when they are in their closed position, thus locking them so that it is impossible to again open the binder without injuring the device. The lids or closures bare provided with downwardly projecting portions 1) which are adapted to close over the key end of the adjusting shaft C thereby sealing it.

With the parts thus arranged as illustrated and described, I secure a temporary binder or loose sheet holder having flexible covers which is very economical in structure and convenient to use.

Any desired leaf or sheet may be quickly and easily'removed or new sheets inserted without in anymanner disturbing those in the binder. The sheets are clamped along theirentire rear edge so that the strain thereon and the liability of tearing the same is reduced to a minimum. The back piece a antomatically telescopes into the pocket in the cover A when the clamping device is adjusted so that the binder always presents an at tractive and neat appearance, no matter what number of leaves or sheets it may be adjusted for.

Another desirable feature of my improved temporary binder or loose sheet holder is that there are no projecting portions, the advantage of which will be readily appreciated.

I have illustrated and described my improved temporary binder or loose sheet holder in the form preferred by me on account of its structural simplicity and economy, although I am aware that it is capable of considerable structural variation without departing from my invention.

Having thus described my invention, What I claim as new and desire to secure by Letters Patent is:

1. The combination of a pair of clamping bars having longitudinal chambers therein and holes in their inner or clamping faces opening into said chambers covers, one of which is provided with a pocket opening at its inner 'end, secured to said clamping bars; a back strip adapted to telescope into said pocket in said cover, connected to the clamping bar of the other cover; a binding cord arranged through the holes in said clamping bars;-threaded blocks to which the ends of said binding cords are secured; an adjusting shaft for said blocks having its ends oppositely threaded, arranged in suitable bearings in the chamber of one of said clamping bars; lids or closures adapted to seal said chambers; and locking dogs adapted to engage said lids or closures to lock them in pheiir closed position, for the purpose specie 2. The combination of a air of clamping bars having longitudinal ciiambers therein and holes in their inner or clamping faces opening into said chambers; covers secured to said clamping bars; a binding cord arranged through the holes in said clamping bars; threaded blocks to which the ends of said binding cords are secured; an adjusting shaft for said blocks having its ends oppositely threaded, arranged in suitable bear:

ings in the chamber of one of said clamping bars; lids or closures adapted to seal said chambers; and locking dogs adapted to engage said lids or closures to lock them in their closed position, for the purpose specified.

3. The combination of a pair of clamping bars having longitudinal chambers therein and holes in their d nner or clamping faces opening into said chambers; a binding cord arranged through the holes in said clamping bars; threaded blocks to which the ends of said binding cords are secured; an adjusting shaft for said blocks having its ends oppositely threaded, arranged in suitable bearings in the chamber of one of said clamping bars; lids or closures adapted to seal said chambers; and locking dogs adapted to engage said lids or closures to lock them in their closed position, for the purpose specified.
